Answer:

the answer is 80%

Step-by-step explanation:

Think of it this way

There is 5 problems wrong out of 25 so 5/25 is the fraction (right/ number of questions)

5/25 can be simplified to 1/5 (divide by 5)

1/5 can be transformed to the percentage 20%

NOW BE CAREFUL 20% is what is WRONG so 100-20=80

so 80% is thus the answer

Answer:

$\frac{12}{19} \times \underline{\bold{-1}} = -\frac{12}{19}$

Step-by-step explanation:

$\frac{12}{19} \times ..... = -\frac{12}{19}$

= $\frac{\frac{12}{19}}{-\frac{12}{19}}$

= $\frac{12}{19} \times -\frac{19}{12}$

= $\bold{-1}$

So, the appropriate value to complete it is -1
